Specification of Letters Patent.

Application filed July 1, 1905. Serial No. 267,877-

To all whom, it may concern.-

Be it known that I GEORGE L. DENGLER, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented new and useful Improvements in Turbine-Engines, of which the following is a specification.

This invention relates to improvements in turbine-engines; and the object of the invention is to provide an engine of simple construction, one that will be positive in action and in which steam, water, air, or other power may be utilized with equal facility.

The entire device consists simply of a casing and a wheel revolubly mounted therein.

The construction of my device will be more fully described in the following specification and clearly illustrated in the accompanying drrwings, in which Figure 1 is a vertical sectional view of my engine. Fig. 2 is a sectional view through line to w of Fig. l.

The numeral 1 designates the foundation and 2 the housing or casing. This housing is made in any desirable form and size and is preferably formed of a ring 2 and two side plates 2". This casing is formed with an inletpassage 4 and an exhaust-passage 5. Inside the casing I form a solid resistance-wall 3, formed integral with the ring 2, and this wall extends over almost the entire smaller space lying between the inlet and exhaust passages.

The numeral 6 designates the turbine-wheel.

This wheel is of simple construction and is provided with a series of peripheral blades 7, equidistantly arranged. These blades are pivoted to the wheel at one end and when not open they rest against the periphery thereof. In the rim of the wheel, under each of the blades 7, I provide a coiled spring 8, seated in an opening 9 in the wheel.

The action is as follows: The wheel 6 moving in the direction of the arrow will always have two of the blades 7 in play. As soon as one of the blades passes the upper edge of the resistance-wall 3 its spring 8 will raise the blade slightly and the steam-supply will at once open it to full-open positionthat is. to right angles with axial line of the wheel. It is at this point that the initial and maximum power is applied, as the full expansive power is utilized by reason of the resistance offered by the wall 3. When the blades approach the lower end of the resistance-wall, they will strike the incline 3 with which it is formed and close against the outer surface of the wheel, compressing the springs 8 and riding along the inner surface of the resistance-wall,thus preventing any escape of steam from the supply-passage. The resistance offered by this contact of the blades against the wall-surface is so slight, however, that it need not be calculated as affecting the action of the engine.

The positive action of the blades, the simple means of opening and closing them automatically, and the simple construction of my entire device, are worthy of consideration, while the resistance offered by the wall 3, assuring the entire power of the steam expansion, is an essential feature.

Having thus fully'described my invention, what I claim, and desire to secure by Letters Patent, is

The combination with the casing, its inlet and exhaust passages and an internal wall having a tapered lower end extending approximately over the entire smaller space lying between said passages, of the turbine-wheel comprising a body and a series of springbacked, equidistant, resistance-blades pivotally mounted on the periphery of said wheelbody, adapted to open to a point at right angles to the axis of the wheel by the action of the steam and to be depressed by contact with the tapered lower end of said wall.

In testimony whereof I affix my signature in presence of two subscribing witnesses.
